SPECIFICATION forming part of Letters Patent N 0. 729,465, dated May 26,1903.

Application filed February 5, 1903- Serial No. 142,019. (No model.)

To all whom it may concern: Be it known that 'I, GEORGE G-.'WELsII,citizen of the United States, residing at Bigspring, in the county ofHoward and State of Texas, have invented new and useful Improvements inCattle-Guards, of which the following is a specification.

My invention relates to cattle-guards; and the object of the same is toconstruct a simple and eificient device of this character which will beeffective for preventing cattle from straying from a wagon-road into theinclosures alongrailroad-tracks.

The simple and novel construction used by me in carrying out myinvention is fully described in this specification and claimed, andillustrated in the accompanying drawings, forming a part thereof, inwhich Figure 1 is a plan view of my device. Fig. 2 is a transversesection of the same on the line 2 2, Fig.- 1. Fig. 3 is a detail of oneof the disks. Fig. 4 is an elevation of a modi fied star-shaped form ofdisk I may use instead of the circular disks.

Like numerals of reference designate like parts in the difierentviews ofthe drawings.

My device is located on a railroad-trackcomprising two rails 1, securedto sills 2, substituted for the usual cross-ties at a point,

where the track intersects a fence and makes a break therein.Rectangular frames 3 are secured to the sills 2 intermediate the rails 1and comprise sides 5 and ends 6, having apertured flanges 5 and 6,respectively, formed thereon. to the sills 2 outside of the track and inalinement with the frames 3. The frames 7 comprise sides 8 and ends 9,which have apertured flanges 8 and 9, respectively, formed thereon.Shafts 10 and 11 are journaled in bearings formed on the sides 5'and 8,respectively, and mounted to revolve on the shafts 10 and 11 are aseries of blunt-edged disks 12, which are loosely mounted thereon andare held against movement longitudinally of Rectangular frames 7 aresecured the'shafts by means of sleeve 13, which leave the disks '12 freeto slightly wabble, since the central aperturesin the disks are roundedOK on the edges. The disks 12 are located to break the intervals.

By the construction just described cattle are prevented from goingthrough the break in the fence or the disks 12 wi1l wabble and turnunder their feet and prevent their securing a foothold thereon. v I donot wish to be limited as to details of construction, as these may bemodified in many particulars without departing from the spirit .of myinvention.

A star-shaped disk 14 is shown in Fig. 4, which may be employed insteadof the circular disk.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a cattle-guard a cylindi-ical'shaft, a series of disks havingcentral apertures therein rounded out on their edges to permit saiddisks to wabble and to rotate on said shaft,

and sleeves mounted on said shaft intermediate said disks,with smallintervening spaces between the ends thereof and the disks, substantiallyas described.

2. In a cattle-guard, the combination of a'
